Getting Apple TV to play music from iTunes using Remote App on iPad

Hi

I play my iTunes Library music on my Apple TV. I use the Remoe App to select songs etc.

However, if I stream (push) from iTunes to Apple TV the subwoofer does not play (this is a well know problem). However, if I pull the music from the Apple TV (by selecting computers) it plays as it should.

When using the Remote App on my iPhone 4S I simply select the Apple TV 3, then select "More" - "Computers" and then the library. Select the music and all is good. When I select More I get all sorts of different options (Albums, Composers, Computers and six others).

However, when I do the exact same thing on the Remote App on my iPad 2 I only get the options of Songs, Playlists, Genres and Composers - but not Computers.

It doesn't seem to make much sense, does it?

I can of course select the iTunes library on the iPad and stream to the Apple TV but then I get the subwoofer problem.

Any solutions?

Thanks!
